## Abstract

A detergent composition useful for laundry applications in both unit dose form and non-unit dose form is described. The detergent composition includes a Maillard reaction inhibiting enzyme that inhibits a reducing sugar present in a sustainable solvent from reacting with an amine source. The detergent composition which includes the enzyme does not undergo yellowing and thus has an increased shelf-life compared to an equivalent laundry detergent composition that lacks such an enzyme.

## Claims

### Claim 1

A unit dose detergent product comprising:
a pouch comprising at least one chamber, the pouch being made of a water-soluble material; and
a detergent composition encapsulated within the at least one chamber, the detergent composition comprising:
at least one surfactant in an amount of from about 15 to about 35 wt % of the detergent composition;
a sustainable solvent comprising a reducing sugar in an amount of from about 0.01 to about 60 wt % of the detergent composition;
an amine source in an amount of from about 5 to about 30 wt % of the detergent composition;
a Maillard reaction inhibiting enzyme in an amount of from about 0.01 to about 3 wt % of the detergent composition; and
water in an amount of from about 5 to about 45 wt % of the detergent composition.

### Claim 2 (depends on 1)

The unit dose detergent product of claim 1, wherein the amine source is selected from the group consisting of an ethanolamine compound, a chelating agent, an amino acid, an amine containing enzyme, and any combination thereof.

### Claim 3 (depends on 1)

The unit dose detergent product of claim 1, wherein the sustainable solvent is selected from the group consisting of sorbitol, xylitol, mannitol, lactitol, isomalt, maltitol, a hydrogenated starch hydrolysate, sucrose, stachyose, verbascose, trehalose, raffinose, and combination thereof.

### Claim 4 (depends on 1)

The unit dose detergent product of claim 1, wherein the reducing sugar is selected from the group consisting of fructose, glucose, hexose, lactose, glyceraldehyde, arabinose, maltose, galactose, ribose, xylose, cellobiose, and any combination thereof.

### Claim 5 (depends on 1)

The unit dose detergent product of claim 1, wherein the Maillard reaction inhibiting enzyme is selected from the group consisting of hexose oxidase, fructosamine oxidase, fructosamine kinase, carbohydrate oxidase, and any combination thereof.

### Claim 6 (depends on 1)

The unit dose detergent product of claim 1, wherein the sustainable solvent is in an amount from about 1 to about 30 wt % of the detergent composition.

### Claim 7 (depends on 6)

The unit dose detergent product of claim 6, wherein the sustainable solvent is in an amount of from about 5 to about 20 wt % of the detergent composition.

### Claim 8 (depends on 1)

The unit dose detergent product of claim 1, further comprising at least one of:
a base in an amount of from about 0.01 to about 2 wt % of the detergent composition;
a weak acid in an amount of from about 0.01 to about 2 wt % of the detergent composition;
a chelating agent in an amount of from about 0.1 to about 2.5 wt % of the detergent composition;
a lauryl sulfate or a lauryl ether sulfate in an amount of from about 2 to about 8 wt % of the detergent composition; or
a fatty acid in an amount of from about 0.5 to about 5 wt % of the detergent composition.

### Claim 9 (depends on 1)

The unit dose detergent product of claim 1, wherein the at least one surfactant is selected from the group consisting of nonionic surfactants, cationic surfactants, anionic surfactants, zwitterionic surfactants, and any combination thereof.

### Claim 10 (depends on 1)

The unit dose detergent product of claim 1, wherein the detergent composition has a pH of from about 6 to about 12.
